On Tuesday night Jon Stewart discussed the recent outbreak of a disease once thought to be eradicated, measles, and the recent trend to not vaccinate your children.
"The Daily Show" host also blasted Senator Rand Paul and Governor Chris Christie for their harmful comments about vaccinations and parental choice.
"The science is clear on it," Stewart said about getting your kids vaccinated. "The only reason we're having this discussion is because of how well vaccines have worked! And they only work when we all do them!"
